TimerService problem(duplicated resource) ----------------------------------------- Key: WFLY-6895 URL: https://issues.jboss.org/browse/WFLY-6895 Project: WildFly Issue Type: Bug Affects Versions: 10.0.0.Final Environment: Two standalone instances connected into a cluster. *Master WildFly* {code} standalone.bat -c standalone-full-ha.xml -Djboss.node.name=master {code} *Slave WildFly* {code} standalone.bat -c standalone-full-ha.xml -Djboss.node.name=slave -Djboss.socket.binding.port-offset=100 {code} Both instances has the same singleton policy defined in singleton-full-ha.xml: {code} <singleton-policy name="scada-singleton" cache-container="server"> <simple-election-policy> <name-preferences>master</name-preferences> </simple-election-policy> </singleton-policy> {code} Reporter: Artur Kowalczyk Assignee: Tomasz Adamski Fix For: 10.2.0.Final, 11.0.0.Beta1 I found a problem with TimerService that occurs when your application is configured as a singleton deployment. *Test Case* # Start master node, the app is also started - OK # Start slave node, the app is deployed but bot stared - OK # Stop master node, the app is started on slave - OK # Start master node, there is a preference for node name so the app will be started again on master and stopped in slave - OK # Stop master node, the app should be started again on slave but an exception occur. - ERROR {code} 09:50:42,115 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-6) MSC000001: Failed to start service jboss.deployment.subunit."wildfly-ejb-in-ear.ear"."wildfly-ejb-in-ear-ejb.jar".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.subunit."wildfly-ejb-in-ear.ear"."wildfly-ejb-in-ear-ejb.jar".INSTALL: WFLYSRV0153: Failed to process phase INSTALL of subdeployment "wildfly-ejb-in-ear-ejb.jar" of deployment "wildfly-ejb-in-ear.ear" at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:154) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1948) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1881) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: WFLYEJB0086: Failed to install management resources for TimerEJB at org.jboss.as.ejb3.deployment.processors.EjbManagementDeploymentUnitProcessor.deploy(EjbManagementDeploymentUnitProcessor.java:82) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:147) ... 5 more Caused by: java.lang.IllegalStateException: WFLYCTL0075: Duplicate resource timer-service at org.jboss.as.controller.registry.AbstractModelResource$DefaultResourceProvider.register(AbstractModelResource.java:290) at org.jboss.as.controller.registry.AbstractModelResource.registerChild(AbstractModelResource.java:169) at org.jboss.as.server.deployment.DeploymentResourceSupport.register(DeploymentResourceSupport.java:322) at org.jboss.as.server.deployment.DeploymentResourceSupport.registerDeploymentSubResource(DeploymentResourceSupport.java:219) at org.jboss.as.ejb3.deployment.processors.EjbManagementDeploymentUnitProcessor.installManagementResource(EjbManagementDeploymentUnitProcessor.java:119) at org.jboss.as.ejb3.deployment.processors.EjbManagementDeploymentUnitProcessor.deploy(EjbManagementDeploymentUnitProcessor.java:79) ... 6 more {code}
